To all L11/'10m er may concern.'

Bc it known that l, Srnrnnn NionoLs, e citizen ci the United States, residing et Denver, in the county of Denver and Stelt@ of Colorado, lieve invented certain new end useful Improvements in Stools, of which the following is e specication.

My invention relates to stools for use of motori/ner., engineers and conductors of reilway curs, end its principal object is to "providein cornbirisdtionl with e stationery supporta e resiliently mounted seat which is adjustable to accommodate persons of dif ferent ststures and to vary its distance from the controller or other apparatus operated @their obiects opt tbe invention reside'in del; of construction all of whichv will be fully disclosed in tbe course of the following description insole with reference to the eccompenying dir-swings.

ln the dressings in the several views of which corresponding parts are similsrly designated,

Figure l represents e side elevetion of my v improved stool;

Figure 2, s section telren on the line 2-2,

Figure l9 eoking upwardly in the direction of the arrows drawn across seid line;

Figure 3, e vertical section along e pleno indicated by the line 3--3, in Figure 2;

Figure il, u rugrnentsry section on the line 1 -4, Figure 2;

Figure 5, e section along 'the line 5--i, Figure l9 drawn to un enlarged scale; end

Figures ti and "Z, similarly enlarged sections teken respectively on the lines tiand 7-7, Figure 1.

Referring more speeicelly to the drew ings, the reference character 2 designates e pedestal composed oit u tubular standard 3 which is estened in en upright` position upon. e ilenged root el.

Tire standard is preferably fastened uon the foot by welding tbe one in on opening of the other end the 'toot lies in its snge 5 b noci, oi' the cer upon which the pedestal is s, number of noles for the passage of bolts ineens of which it 1s fastened to tno su rtefl,

'debly fitted in telescoping relation to tine standard, is e tube t3 which at its up ser end carries en internally screw-'threaded i'errule-shsped liescl 7 to support the corre spondingly threaded stein 8 of the seat of the stoot f 19 which .end of a set screw by which the seut of the lstool is held in its adjusted positions.

The sect consists of e slightly conce'vcd Wooden block 15 provided et its underside' with two parallel' longitudinslly gg'rooved guide members' i which co-oerete with. the slide 2.3 to support 'the seet upon the standard through tire intermediary or the threaded stem', the tubular extension 6 end the spring 9. l l

The members i6 are fastened to t e sont' by screws i7 ond they lieve in o central enelorgenient 1850i' their lower portions, screw threaded Webrings to receive tlie sensoren7 y entering 'the indentetions of the slide plete secures the seat in snyo s, plurality oi predetermined positions.

ln the construction shown in the drawing but one set-screw is used et one side of the seat for the above described purpose', but it Will be apparent tlist two screws may be used st oppositefsirles oi the seat if so desired or that in case the screw-thread of the liole through vvliicli tbe screw passes, should become Worn by long and constant use, the screw con be transferred to. the liole at the other side of the sent and there iei'forrn the seme function ci holding the seat against displacement on the slide plete of the stent 8,

il; is desirable to slightly upset the end ot the set-screw as indicated st 20 in Figure 3 and thereby prevent of its being eccidentellv detached from the guide member with Wliic it is assoeieted.

. Havingtlius described my improved stools` l desire it understood that variations in the construction and cooperative arrangement of the parts thereof be resorted to with in the/scope of :ny invention as delined inV tlie hereunto appended claim.

The stool shown sind described, provides e eoinforteble sont which by reason of its resilient support, seves its occupent trom the unpleasant and frequently harmful effeats of the vibrations and shocks of the vehicle to which the stool is attached; the vertical adjustebility of its sorewthreaded stern in the moving member of the standard pel.'- n'iits of elevating or lowering the'seat ec eording to the stziture of' its occupant and the transverse adjustment of the seat on the stem lallows of its being moved with relation to the controller box or other apparatus to place it within convenient and easy reach of the person who occupies the sent.

What I elnini land desire to secure by Letters Patent is:

A stool of the character described, comprising e seat, spaced parallel guide membeis secured to the Linder side of the seat and provided at their inner opposed edges :with

the said grooves and provided between the ide members y with a depending socket,

seid slide plete being provided in its lower face adjacent each si e edge with depressions arranged et intervals and housed Within and rotected by the grooves of the guide memers, a set-screw mountedn the guide members and arranged' to engage the said depressions foriseouring the slide plate and seat in relative adjustment and e pedestal heving its upper end fitted in the socket of the slide-plate.

In testimony whereof I'have affixed my signature.
